... CC © 2007 Catalyst Semiconductor, Inc. Characteristics subject to change without notice DESCRIPTION The CAT25320 is a 32-Kb Serial CMOS EEPROM device internally organized as 4096x8 bits. This features a 32-byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines ...

... CAT25320 WRITE OPERATIONS The CAT25320 device powers up into a write disable state. The device contains a Write Enable Latch (WEL) which must be set before attempting to write to the memory array or to the status register. In addition, the address of the memory location( written must be outside the protected area, as defined by BP0 and BP1 bits from the status register ...

... To read from memory, the host sends a READ instruction followed by a 16-bit address (see Table 5 for the number of significant address bits). After receiving the last address bit, the CAT25320 will respond by shifting out data on the SO pin (as shown in Figure 8). Sequentially stored data can be read out by simply continuing to run the clock ...
